17 March: Meeting of international collaboration on research and education in Arctic science take place                  in ILTS on 18 March. The programme is available here.

   Introduction of the workshop

Greenland is rapidly losing ice under the pronounced warming in the Arctic region. Increasing amount of snow and ice melt is an important driver, but other processes such as glacier acceleration and surface albedo reduction are also affecting the ice mass loss. In particular, tide-water glaciers are rapidly retreating under the influence of changing ocean. In turn, the increase in freshwater and sediment discharge from the glaciers has an impact on the ocean environment. Such interactions among atmosphere, ice and the ocean play important roles in global and Arctic environmental change.

Since 2012, Joint Research Program of the ILTS has been hosting annual workshop on the mass loss of the Greenland ice sheet and its impact on global environment. The workshop aims to coordinate recent Japanese research activities in Greenland, which include GRENE Arctic Climate ChangeResearch Project, SIGMA projection snow impurity and glacial microbes, and NEEM and JSPS funded ice core drilling projects. In September 2015, ArCS (Arctic Challenge for Sustainability) project has launched to take over the GRENE project to continue integrated Arctic research. ILTS plays a central role in one of the ArCS research projects, "Ice-ocean interaction in northwestern Greenland". This project is carried out also as a program of ILTS Joint Research Division.

This international workshop is co-organized by ILTS and the ArCS ice-ocean project with additional funding from SIGMA project. The workshop aims to sum up the recent Japanese research projects, and discuss future research activities in Greenland. We invite leading scientists from over the world to share current understanding of the rapidly changing Greenland, as well as to discuss future research activities and collaborations.
